said Holmes. "It must be very familiar to you. Have you not tethered a
young kid under a tree, lain above it with your rifle, and waited for
the bait to bring up your tiger? This empty house is my tree, and you
are my tiger. You have possibly had other guns in reserve in case there
should be several tigers, or in the unlikely supposition of your own aim
failing you. These," he pointed around, "are my other guns. The parallel
is exact."

Colonel Moran sprang forward with a snarl of rage, but the constables
dragged him back. The fury upon his face was terrible to look at.

"I confess that you had one small surprise for me," said Holmes. "I did
not anticipate that you would yourself make use of this empty house and
this convenient front window. I had imagined you as operating from the
street, where my friend, Lestrade and his merry men were awaiting you.
With that exception, all has gone as I expected."

Colonel Moran turned to the official detective.

"You may or may not have just cause for arresting me," said he, "but at
least there can be no reason why I should submit to the gibes of this
person. If I am in the hands of the law, let things be done in a legal
way."

"Well, that's reasonable enough," said Lestrade. "Nothing further you
have to say, Mr. Holmes, before we go?"

Holmes had picked up the powerful air-gun from the floor, and was
examining its mechanism.
